How to Change VVDI Benz FBS3 KeylessGo Key Frequency?

Similar as Xhorse VVDI BE key pro, users can exchange the VVDI MB FBS3 keylessgo smart keyfrequency between 315MHz and 433MH.

The reusable FBS3 smart key is compatible with most Mercedes key programmers on the aftermarket.

2 Ways to exchange frequency:

Method 1:

If you have VVDI MB Tool, it is easy to change frequency in vvdi mb software (update software to latest version)

Select Other Function-> Set key remote frequency/ Update MB smart key 

You can set frequency between 315MHz and 433MHz

Method 2: 

If without VVDI MB, you can change FBS3 keylessgo smart key frequency manually by soldering/desoldering the FRE resistor (marked red in picture below)

Read Benz W211 HC12 by VVDI Prog, Xprog or R270

Question:

I have w211 HC12 EIS 211 545 10 08 (3K91D). Xhorse VVDI Prog manual says use cable V3 but on picture with connection there is V1 cable (it tell to use V2 or modify V1).

In VVDI Prog software, I select EIZ-W211 (HC12), it failed to read and said chip crack failure.

So which cable do I need to use? Need be 100% sure which cable to use, in order to avoid (or minimalize) risk with that tricky 3k91d.

Anyone succeed reading W211 HC12 EIS with VVDI Prog recently?

Solution:

Use MCU Reflash Cable V3 to read this mcu (confirmed by Xhorse engineer)

There is a new adjustment v3 for mcu cable.

Then try with 12v adaptor to vvdiprog

Choose correct EIS type

MCU reflash cable V2 modified to V3

FYI:
vvdi-prog can read W211-ST very fast.  For HC12 need mcu cable modification.
Read w211 HC12 with R270 programmer no problem (new R280 should be ok)
R270 can read W211 HC12 eeprom and flash
Choose the correct masket of mcu of R270

Tried Xprog 5.0 clone, read successfully, keys generated and EIS is working with new keys.

Blue R260 clone also read this MCU no problem but with some software trick.
W211 has 0K50E and 3K91D

VVDI Prog Pinout to Alfa BCM MC9s12DG256

Question:
Any option to get pinout BCM for carprog or vvdi prog? Can’t find anything ?
I have this Magneti Marelli BCM alfa brera.

MCU MC9s12DG256 CPVE
0L01Y
QQPRO752

Any idea how to connect it ? Any option for pinout ?

Solution:

Smok or I/O terminal can read Alfa 159 by OBD.

Don’t use carprog. Use Orange5, Upa or vvdiprog.

It is not so difficult to follow the pins, and to a spot to connect a wire.
Did it 2 weeks ago on alfa spider with vvdi-prog
MC9s12DG256 BCM pinout to vvdiprog

Read BCM data, then precode the key with correct tool otherwise the remote will not work. After that have to add the key via OBD.
You can use original key fob but if the precode correct then you can use PCF7936 as well.
